摘要： Water blown, thermosetting unsaturated polyester-polyurethane hybrid foam compositions are formed by the reaction of an A side composition and a B side composition. The A side composition comprises a polyfunctional isocyanate compound and a free radical initiator. The B side composition comprises a mixture of: (i) an ethylenically unsaturated monomer solution having dissolved therein about 30-90 weight percent of a polyester polyol having at least one ethylenically unsaturated group per molecule which has predominantly hydroxyl end groups; (ii) an amine compound having two or more primary or secondary amine groups in an amount effective to react with the A side composition to form small urea domains finely dispersed within a continuous polyester-polyurethane hybrid phase; and (iii) about 25 to about 150 equivalents water based on 100 equivalents of active hydrogen in the B side. When the A and B side compositions are reacted, the composition will have a ratio of active NCO groups of the isocyanate to active NH groups of the amine compound of between about 10:1 and about 50:1. and an isocyanate index, NCO:(NH+OH+COOH+HOH), of between about 0.5 and about 2.0.

摘要： Compositions for forming polymeric layers useful in the manufacture printed wiring boards and other electrical interconnecting devices are disclosed. The compositions typically are processable in aqueous base and can be made photosensitive with the addition of a positive acting photosensitive compound. The compositions are particularly useful in the manufacture of laminable films used to make printed wiring boards. Multilayer printed wiring boards made using such films, and methods for making and using the films and boards, also are disclosed.
